Nerve
sheath myxoma(NSM) is a rare cutaneous neoplasm of uncertain histogenesis. NSM can
be divided into two groups; NSM1 (a myxoid NSM) and NSM2 (a cellular neurothekeoma).
NSMs are characterized histologically by well-defined, lobular or plexiform dermal
proliferation of stellate, spindle-shaped cells embedded in abundant myxoid stroma.
A variable amount of nerve fascicles are entrapped within and around the tumor.
Two variants of NSM share the same features to a certain degree but differ in cellularity
and mucin deposition. We report two cases of NSMs with different clinical and histopathologic
features. (Ann Dermatol 12(3) 215~217, 2000). |
